Clay Research
Clay minerals are typically formed over long periods of time by the gradual
chemical weathering of rocks, usually silicate-bearing, by
low concentrations of carbonic acid and other diluted solvents.
These solvents, usually acidic, migrate through the weathering rock after leaching through upper weathered layers. In
addition to the weathering process, some clay minerals are formed by hydrothermal activity. Clay deposits may be
formed in place as residual deposits in soil, but thick deposits usually are
formed as the result of a secondary sedimentary deposition process after they have
been eroded and transported from their original location of formation. Clay
deposits are typically associated with very low energy depositional environments such as large lakes and
marine basins.
Primary clays, also known as kaolins, are located at the site of formation.
Secondary clay deposits have been moved by erosion and water from their primary
location.[2]

Clay Animals
Our project has to do with dealing with clay. Down below are pictures of animals that stood out to me or I liked in some sort of way. The descriptions tell why I like or choose them. We are to pick one animal of our choice, and make it into a clay sculpture! I am looking forward to this project, the only hope is it turns out good!
